A closer look at intraspecific variation of Cerataphis brasiliensis (Hempel) (Hemiptera: Hormaphididae)
Neotropical Entomology 37 (2), 137-142
Abstract: The aim of our study was to characterize Cerataphis brasiliensis Hempel, an aphid of native palm tree of tropical savannas (cerrado), and to record intraspecific variation. We found two parthenogenetic forms of apterous viviparae females of C. brasiliensis. We differentiate the two forms through measurable and qualitative characters: (i) length of cephalic horns, (ii) number of antennal segments, (iii) presence or absence of wax glands, (iv) location of siphunculi.
